I've done the belt a couple times, but haven't had anything like that happen so this is just a guess. I'd probably start with trying to rotate the intake cam CCW back into place (it's already swept that area, so likely no further damage doing that). I'm not sure what spring tension is in that position though. I'd probably try to fit the locking tool at that wrong angle, and see if I can use it to rotate the cam back. Failing that, I'd see if I can hold it while tightening up the cam bolt enough to be able to use the pulley as well to turn it ccw with the lock tool at the same time back into the locked position.
